Fleet Foxes frontman Robin Pecknold hasn't performed live in public for two years, since his Seattle folk band wrapped their tour behind 2011's Helplessness Blues. Pecknold ended his hiatus of sorts Tuesday night by covering Pearl Jam's "Corduroy" on Late Night With Jimmy Fallon with help from Grizzly Bear's Daniel Rossen. First thing's first: Pecknold got a serious hair and beard trim during his time away. Just sayin'. Watch above.

The cover is part of a week-long celebration of Pearl Jam's catalogue on Late Night to coincide with the release of their new album, Lightning Bolt. Soundgarden's Chris Cornell also appeared alongside the Avett Brothers to play "Footsteps." Watch below.

PJ guitarist Mike McCready will perform with country star Dierks Bently and the Roots tonight, and the veteran Seattle band will wrap up with week by playing Lightning Bolt tracks on both Thursday and Friday night.
